Handling reorder event

[DenisCL]

Hi,

I'm trying to block reordering of a gridview column.

In my sample, I've three columns. The first one got IsReorderable = false. Others are true.
But I can move the second and the third column at the first index, and I want to block that because this is a sort of reordering the initial first column.

I've inspected the DropInfo and DragInfo to the grid, and I can see the e.Options.Payload containing something called :
Telerik.Windows.Controls.GridView.HeaderCellReorderOptions;
having my informations : CurrentDisplayIndex and InitialDisplayIndex.

But I'm unable to cast the object with this type, and play with them.

Any idea ?
Thanks.

Well, basically achieved with grid ColumnReordering event.

But is there a way to programmatic display a "DropImpossible" cue template ?

Well, they discribes what I've done with the ColumnReordering event.
Basically, I want to have the class Telerik.Windows.Controls.GridView.HeaderCellReorderOptions public, so I can handle the reordering possibility before the user drop the column (during the DropInfo).

Hi DenisCL,

May you specify what is the purpose you want the above mentioned class to be public ? How do you want to use it ? Furthermore, may you provide a bit more details about your scenario ? Are the links not helpful ?
Any relevant information about your settings, the ColumnReorderOptions, etc. will be useful.
